The curvature of n-dimensional Riemannian manifold is given by an antisymmetric n×n matrix of 2-forms (or equivalently a 2-form with values in , the Lie algebra of the orthogonal group , which is the structure group of the tangent bundle of a Riemannian manifold).
After Rudge's death, his company was merged with The Tangent & Coventry Tricycle Company to form D. Rudge & Co. which in 1894 became Rudge Whitworth Cycles.
